The D23-LB is a LoRaWAN Temperature Sensor for an Internet of Things solution. D23-LB will convert the Temperature reading to LoRaWAN wireless data and send it to the IoT platform via the LoRaWAN gateway.
The LoRa wireless technology used in D23-LB allows devices to send data and reach extremely long ranges at low data rates. It provides ultra-long range spread spectrum communication and high interference immunity whilst minimizing current consumption.
The temperature sensor used in D23-LB can measure -55°C ~ 125°C with accuracy ±0.5°C (max ±2.0 °C).
D23-LB supports the temperature alarm feature, the user can set a temperature alarm for instant notice. D23-LB supports the Datalog feature, which can save data when there is no LoRaWAN network and uplink when the network recovers.
D23-LB supports BLE configuration and wireless OTA update, which makes user easy to use.
D23-LB is powered by an 8500mAh Li-SOCI2 battery, it is designed for long-term use up to 5 years.
Each D23-LB is pre-loaded with a set of unique keys for LoRaWAN registrations, register these keys to the local LoRaWAN server, and it will auto-connect after power on.
